Okay so before this it started first time every time, but the other day i went to start it, the battery was flat, so I hooked jumper battery on, it struggled for a little bit but eventually kicked over. Then i stopped it, came back to the car 5 minutes later to start it again, put the jumper back back on just in case, and it sounded like it turned over slowly one or twice, then nothing everything on the dash went off, stereo went off, nothing. I dont think it could be the battery because with the jump pack on I tested it with a multimeter and it was at 12.3v. I have no idea what this could be because it would start once, but not again.

Check all your connections. Clean your earths, and try a different battery from another car, if that dies too, it's ur alternator.

yep try another battery 12.3 volts for a battery aint that crash hot

It could be 1 of 3 things. -Battery to low in charge. Place the battery on a charger & trickle charge it for half a day. Or buy a new battery. -Alternator is not charging the battery enough. Check your belts & place a multi meter on when the car is running. should be 14volts or more when running & less when the engine is stopped. -Starter motor might be tried. Think of how many times in it's life time has it started your car. Does the engine crank over slowly? Some original photos have not been recovered yet.
